Key Term Definitions

ECHO Cancellation and Suppression:
With the cancellation and suppression processes, information is only sent across the line when someone is actually speaking, so when a person stops talking the signal is cut off.

Acoustic Clarity Technology:
This Polycom patented technology allows you to enjoy instantaneous natural conversation. When paired with a full duplex speakerphone, echo is eliminated and both callers are able to speak simultaneously.

Full Duplex Operation:
The full duplex feature allows simultaneous flow of audio signals between your conferencing phone and that of the outside caller.

SIP VoIP:
When broken down into 2 parts, SIP and VoIP are acronyms for Session Initiation Protocol and Voice Over Internet Protocol. The SIP and VoIP features move voice traffic through IP networks instead of traditional circuit-switched networks.
